## What is vigram App?

vigram App is the companion app for viDoc® and viDoc® light — the RTK GNSS receivers from vigram AG that turn a smartphone into a professional tool for surveying and smart documentation.

CONNECT IN SECONDS
Switch your viDoc on, hold it close to your iPhone and it appears. vigram connects over Bluetooth and shows what you are holding: model, serial number, device index, firmware and hardware version, and battery level.

SEE WHAT YOUR VIDOC MEASURES
Watch your viDoc work in real time: the satellites it uses, its own accuracy estimate for each axis, and the HDOP, PDOP and VDOP values. As soon as it has a position, you get latitude and longitude in WGS 84, the height above sea level, the ellipsoidal height and the geoid separation. Copy a reading with one tap and paste it into a message or a report. Indoors the screen tells you why there is no position yet — the viDoc needs open sky, and nothing is wrong with it.

ALWAYS ON THE RIGHT FIRMWARE
vigram App asks vigram AG which firmware fits your exact device and, when a newer one is published, installs it for you. The update is guided step by step, with animations that show which button to press and when. The result is confirmed by the device itself: vigram App reads the version back from your viDoc before it calls the update done.

KNOW YOUR DEVICE
Datasheet values for your model, a guide to how an update works, and a direct line to vigram AG support with the details support needs already filled in.

PRIVATE BY DESIGN
Your viDoc's position is shown on screen and never leaves your iPhone unless you copy it yourself. Notifications about new firmware and news from vigram AG are optional, and each can be switched off on its own.


Requires a viDoc® or viDoc® light. Learn more at vidoc.com.
